ABSTRACT:
An ac motor comprises a dc micromotor with terminals passing through an insulating end bell to receive dc current from a rectifier module. The flat surface of the end bell contains fixing grooves and a hole. The rectifier module is fitted within the hole. Fixing bosses are also provided on the end surface of the end bell. An input terminal plate is provided with holes for engaging the four bosses. The input terminal plate is provided with cut grooves which delimit four input terminal portions. The input terminal plate also has a middle hole. The input terminal plate is pressed into engagement with the four bosses resulting in the input terminal plate separating into four input terminal pieces, which are bent into the fixing grooves and also bent into the hole to fixedly fit the input terminal pieces to the end bell. Terminals of the rectifier module are electrically and mechanically connected to be held by the input terminal pieces.
